Cryosurgery (cryotherapy) is the use of extreme cold in surgery to destroy abnormal or diseased tissue; thus, it is the surgical application of cryoablation.

The term comes from the Greek words cryo (κρύο) ("icy cold") and surgery (cheirourgiki – χειρουργική) meaning "hand work" or "handiwork".

Infrared radiation (IR) is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore generally invisible to the human eye (although IR at wavelengths up to 1050 nm from specially pulsed lasers can be seen by humans under certain conditions).

It is sometimes called infrared light.

IR wavelengths extend from the nominal red edge of the visible spectrum at 700 nanometers (frequency 430 THz), to 1 millimeter (300 GHz) Most of the thermal radiation emitted by objects near room temperature is infrared.

Like all EMR, IR carries radiant energy, and behaves both like a wave and like its quantum particle, the photon.

A machine uses power to apply forces and control movement to perform an intended action.

Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement.

They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems.

A vacuum cleaner, also known as a sweeper or hoover, is a device that uses an air pump (a centrifugal fan in all but some of the very oldest models), to create a partial vacuum to suck up dust and dirt, usually from floors, and from other surfaces such as upholstery and draperies.

A treadmill is a device generally for walking or running or climbing while staying in the same place.

Treadmills were introduced before the development of powered machines, to harness the power of animals or humans to do work, often a type of mill that was operated by a person or animal treading steps of a treadwheel to grind grain.

In later times, treadmills were used as punishment devices for people sentenced to hard labour in prisons.

The terms treadmill and treadwheel were used interchangeably for the power and punishment mechanisms.
